Import gizmo in Nuke with File ⇒ Insert Comp Node

This scripts works mainly with the Normal Pass using the IDistort nodes it allows to deform a shape, working with these
informations you'll be able to add fake volume-deformations on simple shapes without any render;

To achieve that we need to work a little bit with Nuke's Expressions to use the potential of the R, G and B values of our Normal
Pass, to make it easier the node have some Preview checkboxes so you can preview what you're writing, activating the High Quality
Blur will be a bit more time consuming but result is way better.
